What is the standard form of the polynomial function
p(x) = - 2x4 + x6 + 3x + 1 ?
p(X) = x6 - 2x4 + 3x + 1
p(x) = 1 + x6 - 2x4 + 3x
p(x) = x6 - 2x4 + 1 + 3x
p(x) = - 2x4 + 3x + x6 + 1
- 18. Multiple Choice
What is the standard form of the polynomial function
p(x) = 8x2 + 4x + 3x6 + 3 ?
p(X) = 3x6 + 3 + 8x2 + 4x
p(x) = 3x6 + 8x2 + 3 + 4x
p(x) = 3x6 + 8x2 + 4x + 3
p(x) = 3x6 + 3 + 4x + 8x2
